HOLLOW-TILE BUILDING BLOCK.

Application filed December 3G, 1922.

To all whom t may con-cem Be it known that I, DAvID R. BONE, a citizen of the United States, residing at Oglesby, in the county of Coryell and State of Texas, have invented new and useful Improvements in Hollow-Tile Building Blocks, of which the following is a. specitication.

This invention relates to hollow tile building blocks, also to a wall-assembly construct ed of such blocks.

IVhere a wall assembly is of such construction that a mortar-joint extends straight through the assembly, the moisture can penetrate from the exterior to the interior with comparatively little resistance, as compared with a wall assembly in which the mortar-j oints are broken by vertical portions which imposes the resistance of the force of gravity against the force of capillary attraction, and at the same time lengtlr ens the mortar-joints, thus imposing additional resistance to the entrance of moisture to the interior. Therefore, one object of this invention is to provide a building' block ot such construction that it will impose the above mentioned resistances when assem* bled with others of its kind and others of an ordinary or cubical form, And another object, in a block of this character, is to insure an interlocking of all the bloclrs ot' the wall-assembly- A further object is to provide a cruciform block ot such character that it may be assembled and united with four cubical blocks so as to form a block or wall-section having a tongue at one side and a groove at the other side, so any number of such wall-sections can be united in tongued and grooved and interlapped relation for forming a wall, and which can be properly terminated or finished by the addition of separate units such as those of which it is composed, or any desired or required fractional part of such units.

In the accompanying dra-wings, in which similar reference characters correspond to similar parts in the several views:

Fig. 1 is an elevation of one of the main or cruciform blocks or units: Fig. 2 is an elevation of one of the cubical blocks or units such as I prefer to use to form part of the exterior side of the wall or wallsection: Fig. 8 is an elevation of one of the cubical blocks or sect-ions such as I prefer to use to form part of the interior side of the wall or wall-section: Fig. 4 is an ele- Serial No. 610,048.

de'line the limits of each unit: And Fig.

5 is an elevation7 in perspective, of a wallassembly having at one end two cruciform blocks and six cubical blocks, showing how the units of Figs. l, 2 and 3 (one each) are assembled on top of one of the wallsections of Fig. 4.

In the several views, the several units are respectively represented by the numerals 1, 2 and 8. The cruciform blocks are each formed with a middle or mid-wall portion which is the same height as the lateral extent of the block, and consists of three cells which are approximately equal in size and shape. The lateral extent of this uprightportion is substantially one-third of the vertical extent. It is formed with opposed lateral extensions lau which are cubical, and each of these extensions consists of one cell substantially the same as those of the middle upright part; so the lateral reach of each part lu is equal to thelateral extent of said upright middle part. The centers of these lateral extensions are in the same horizontal plane with the partition that separates the two upper cells of the middle upright part; so the latter extends one-halt of its length below these extensions, and one-sixth of its length above them, the other one-third of its length being between them. The lateral and vertical extent of each part la is approximately the same as that of each of the units 2 and 3, allowing a slight dit terence to compensate for the mortar-joints between these extensions and units; thereby providing for the assembling to form the section and wallassembly shown in Figs. 4iand 5.

Figures a and 5 show clearly how the mortar joints are oliset orbrolren at each onethird the distance through the wall, and how the units interlap through a vertical section of the wall. Fig. 5 also shows how the units are interlapped longitudinally, and how, in spite of such interlapping of the units, a plane wall-end or finish is obtained by providing the units in single lengths and double lengths: VHowever, the longitudinal interlapping may be obtained in other ways and by other assemblies of the blocks or units;

for instance, by assembling them in groups of live, as shown in Fig. il, then uniting the units by means o' cement or mortar, thus forming the above defined wall-sections each having a tongue and a groove at its lower and upper ends. lt is obvious that these wall sections can be assembled to form a wall having tongue-and-groove joints and broken vertical joints, by interlapping these wall-sections so that each course' breaks the joints of the courses above and below it.

As this crucitorm building block is capable of numerous advantageous applications, as -partly shown in the foregoing, it is not intended to limit my protection by conforming to any particular one oi such ap plications; but what l claim as my invention is:

l. The cruciforin building block of which the upright middle part is substantially three times as high as' its lateral width and is formed with lateral extensions which are horizontally opposite to one another and are substantially equal in height and lateral extent to the lateral width of the said middle part, said middle part extending above the lateral extensions about one-halt1 the distance of itslateral extent, said middle part extending below said lateral extensions about one and one-halt times the distance of its lateral extent, substantially as shown, for the purpose specified.

2. The crucii'orm building block which includes an upright middle part formed of three substantially equal cells separated by laterally or horizontally disposed partitions the upper one of which is substantially twice -tlie distance from the bottom as from the top, this central upright part `being formed with two horizontally opposite extensions each consisting of one cell substantially equal to the cells of said upright part, the centers of these lateral extensions being substantially in the same level with the said upper partition, the upright part extending above the lateral extensions a distance of about one-hall the height of each lateral extension, the upright part extending below the lateral extensions a distance of about one and one-half times the height of each lateral extension, the lateral extent ot' the iqnright pari and of each lateral extension being substantially equal to the height of the latter.

3. The combination of a cruciform build ing block having its lateral extensions substantially equal in height and lateral extent to the lateral extent of the middle in :night part, said lateral extensions being nearer the upper end and 'farther from the lower end ot' the middle upright part than the lateral extent of the latter, the lateral extent of said middle upright being substantially equal to the lateral extent and to the height ot each lateral extension; and four rectangular blocks in the angular spaces above and below the lateral extensions, thus forming a wall-section having a tongue at one side and a groove at its opposite side, substantiallyY as shown, for the purposes specified.

ln testimony whereofl have aiixed my signature.
